Description

Technical Field

[0001] This invention relates to the field of fuel tank manufacturing technology, and in particular to a welding station with a cooling line located above the weld line. Background Technology

[0002] During the manufacturing process of fuel tanks, welding is required to enable them to perform their intended functions. After pre-processing of the fuel tanks by upstream lines such as blow molding or stamping lines, the tanks are fed into the welding line for welding. During the pre-processing, the temperature of the fuel tanks output from the upstream lines is usually higher due to the influence of process temperature and equipment heat. When the temperature of the fuel tanks delivered to the welding line does not meet expectations, the welding quality is poor. In existing technologies, due to space constraints in the production area, fuel tank production must be completed in a small space. The overall temperature of the fuel tanks is easily raised under the influence of the production environment, and it is difficult to cool the tanks within the limited space, resulting in poor welding quality. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a welding station with a cooling line positioned above the welding line, which can improve the welding quality of oil tanks. The welding line is used for welding oil tanks; the cooling line is located on top of the welding line and includes a conveying device and multiple cooling devices. The conveying device has a loading station, multiple cooling stations, and a unloading station arranged sequentially along the conveying direction. The loading station is used to receive oil tanks, and the multiple cooling devices are respectively arranged at corresponding cooling stations and used to cool the oil tanks. The lifting device includes a lifting drive mechanism and a clamping mechanism. The lifting drive mechanism is connected to the clamping mechanism and can drive the clamping mechanism to move vertically between a first position and a second position. When the clamping mechanism is in the first position, it can clamp the oil tank located at the unloading station; when the clamping mechanism is in the second position, it can place the oil tank onto the welding line.

[0004] The welding station with the cooling line positioned above the welder in the embodiments of the present invention has at least the following beneficial effects: The conveying device transports the oil tank from the loading station through multiple cooling stations to the unloading station, and the lifting device transfers the oil tank from the unloading station to the welding line. Multiple cooling devices at these stations cool the oil tanks, reducing the risk of overheating and ensuring the welding line can weld oil tanks at the expected temperatures. The conveying device and multiple cooling devices are located at the top of the welding line, minimizing the footprint and enabling cooling of the oil tanks within a limited space, thereby improving the welding quality.

[0005] In one embodiment of this implementation, the cooling device includes a first fan located at the bottom of the transmission device.

[0006] In one embodiment of this implementation, the cooling device includes a second fan and a guide member. The guide member has a guide surface inclined to the vertical direction. The guide member is located on the top side of the transmission device, and the second fan is located on the side of the guide member facing away from the transmission device. The second fan is used to output airflow to the oil tank.

[0007] In one embodiment of this implementation, the second fan has a second air duct, the axis of which is parallel to the guide surface, and the second air duct is used to output airflow.

[0008] In one embodiment of this implementation, the conveying device includes a conveyor belt extending perpendicular to the horizontal direction, and a plurality of cooling devices are arranged in the horizontal direction. The conveyor belt is used to transport the oil tank in the horizontal direction.

[0009] In one embodiment of this implementation, a lifting drive assembly and a lifting assembly are further included. The lifting assembly and the clamping mechanism are arranged at intervals in the horizontal direction and are used to connect the oil tank. The lifting drive assembly is connected to the lifting assembly and can drive the lifting assembly to move in the vertical direction so that the lifting assembly can transfer the oil tank from the front line to the loading station.

[0010] In one embodiment of this implementation, the clamping mechanism includes a clamping member, a clamping driver, an adjusting driver, and a plurality of elastic clamping blocks. The clamping member is movably connected to the transmission device. A lifting driving mechanism is connected to the clamping member and can drive the clamping member to move in the vertical direction. The plurality of elastic clamping blocks are movably disposed on the clamping member. The clamping driver is connected to the elastic clamping blocks and can drive the elastic clamping blocks to move in the horizontal direction so that the plurality of elastic clamping blocks clamp the oil tank. The adjusting driver is connected to the clamping member and can drive the clamping member to rotate around an axis parallel to the vertical direction.

[0011] In one embodiment of this implementation, an isolation plate assembly is also included, with the isolation plate assembly located on the top side of the welding line and the cooling line located on the side of the isolation plate assembly facing away from the welding line.

[0012] In one embodiment of this implementation, the welding station on the cooling line includes a movable plate and a movable driver.

In the open position, the conveying port is exposed. The clamping mechanism can move to both sides of the isolation plate group through the conveying port.

[0013] In one embodiment of this implementation, the movable plate and the isolation plate assembly are movably connected in the horizontal direction.

[0022] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0023] Please see Figures 1 to 3 , Figures 6 to 7 , Figure 1 This is a three-dimensional structural diagram of a welding station 100 with a cooling line located in one embodiment of the present invention; Figure 2 yes Figure 1 A top view of the welding station 100 located on the cooling line; Figure 3 yes Figure 1 A three-dimensional structural diagram of part of the transmission device 11 and cooling device 12; Figure 6 yes Figure 1 A schematic diagram of part of the structure of the lifting device 20, the lifting drive assembly 31, and the lifting assembly 32; Figure 7 yes Figure 1 A three-dimensional structural schematic diagram of the clamping mechanism 22. This embodiment of the invention provides a welding station 100 with a cooling line mounted on it, which includes a welding line, a cooling line 10, and a lifting device 20. The welding line is used for welding the oil tank 200; the cooling line 10 is located on the top side of the welding line and includes a conveying device 11 and multiple cooling devices 12. The conveying device 11 has a loading station 111, multiple cooling stations and a unloading station 112 arranged sequentially along the conveying direction. The loading station 111 is used to receive the oil tank 200, and the multiple cooling devices 12 are respectively arranged in the corresponding cooling stations and are used to cool the oil tank 200; the lifting device package 20 includes a lifting drive mechanism 21 and a clamping mechanism 22. The lifting drive mechanism 21 is connected to the clamping mechanism 22 and can drive the clamping mechanism 22 to move vertically between a first position and a second position. When the clamping mechanism 22 is in the first position, the clamping mechanism 22 can clamp the oil tank 200 located at the unloading station 112. When the clamping mechanism 22 is in the second position, the clamping mechanism 22 can place the oil tank 200 onto the welding line.

[0024] Specifically, the welding line is parallel to the Z-direction vertically and includes a welding conveyor line and a welding robot. The welding conveyor line is used to transport the oil tank 200, and the welding robot is used to transfer the parts to be welded to the oil tank 200 on the welding conveyor line and weld the parts to be welded to the oil tank 200. The transmission device 11 includes a first conveyor line 113, a second conveyor line 114, and a third conveyor line 115. The first conveyor line 113 and the third conveyor line 115 extend along the X-direction and are arranged at intervals along the X-direction. The end of the first conveyor line 113 facing the third conveyor line 115 constitutes a loading station 111, and the end of the third conveyor line 115 facing the first conveyor line 113 constitutes a unloading station 112. The second conveyor line 114 extends along the X-direction and is located on one side of the first conveyor line 113 and the third conveyor line 115 along the Y-direction. The first conveyor line 113, the second conveyor line 114, and the third conveyor line 115 each include a rotary motor, a pulley, and a belt. The belt extends along the X direction and is used to carry the oil tank 200. The outer circumferential surface of the pulley is connected to the belt. The drive shaft of the rotary motor is perpendicular to the Z direction. The rotary motor is connected to the pulley and can drive the pulley to rotate around an axis perpendicular to the Z direction, so that the pulley can drive the belt to convey the oil tank 200 along the X direction. Thus, the first conveyor line 113, the second conveyor line 114, and the third conveyor line 115 can all convey the oil tank 200 along the X direction. A first slide 116 is provided between the first conveyor line 113 and the second conveyor line 114. The first slide 116 can slide along the Y direction to the first conveyor line 113 and the second conveyor line 114. A second slide 117 is provided between the second conveyor line 114 and the third conveyor line 115. The second slide 117 can slide along the Y direction to the second conveyor line 114 and the third conveyor line 115 so as to transfer the oil tank 200 from the second conveyor line 114 to the third conveyor line 115. The first slide 116 and the second slide 117 are arranged at intervals along the Y direction. The first conveyor line 113 can receive the oil tank 200 from the loading station 111 and transfer the oil tank 200 from the loading station 111 to the first slide 116 along the X direction. The first slide 116 can transfer the oil tank 200 from the first conveyor line 113 to the second conveyor line 114. The second conveyor line 114 can transport the oil tank 200 from the first slide 116 to the second slide 117 along the X direction. The second slide 117 can transfer the oil tank 200 from the second conveyor line 114 to the third conveyor line 115. The third conveyor line 115 can transport the oil tank 200 from the second slide 117 to the unloading station 112 along the X direction.

[0025] It should be noted that, in some embodiments, the cooling device 12 includes an electric pump assembly and copper pipes that can contact the oil tank 200. The electric pump assembly can deliver fluid through the oil tank 200 to transfer heat from the oil tank 200. Multiple cooling devices 12 are divided into a first group, a second group, and a third group. Multiple cooling devices 12 in the first group are arranged along a first conveyor line 113 and are used to cool the oil tank 200 located on the first conveyor line 113. Multiple cooling devices 12 in the second group are arranged along a second conveyor line 114 and are used to cool the oil tank 200 located on the second conveyor line 114. Multiple cooling devices 12 in the third group are arranged along a third conveyor line 115 and are used to cool the oil tank 200 located on the third conveyor line 115.

[0026] It should be noted that, in some embodiments, the clamping mechanism 22 includes a gripper driver and multiple grippers, which are movably connected. The gripper driver connects to the grippers and can drive the multiple grippers to move relative to each other in a direction perpendicular to the Z-direction, so as to clamp the oil tank 200 between the multiple grippers. The lifting drive mechanism 21 includes a linear motor with a driving direction parallel to the Z-direction, and can drive the clamping mechanism 22 to move vertically upward. In the projection plane perpendicular to the Z-direction, the orthographic projection of the clamping mechanism 22 is arranged in the X-direction between the orthographic projection of the first conveyor line 113 and the orthographic projection of the third conveyor line 115. The third conveyor line 115 can output the oil tank 200 from the unloading station 112 in the X-direction, so that the oil tank 200 is clamped by the clamping mechanism 22 located on one side of the unloading station 112 in the X-direction. The lifting drive mechanism 21 can drive the clamping mechanism 22 to move vertically downward, and the clamping mechanism 22 transfers the oil tank 200 from the unloading station 112 to the welding conveyor line of the welding line.

[0027] It should be understood that in some embodiments, the lifting drive mechanism 21 can drive the clamping mechanism 22 to move vertically upward, and the clamping mechanism 22 can transfer the oil tank 200 from the welding line to the loading station 111, so that the transmission device 11 can transport the oil tank 200 from the loading station 111 to the cooling device 12. This arrangement can cool the semi-finished oil tank 200 during the welding process, which is beneficial to further improve the welding quality of the oil tank 200.

[0028] The welding station 100 of the present invention, with its cooling line positioned above the welding line, includes a conveying device 11 that transports the oil tank 200 from the loading station 111 through multiple cooling stations to the unloading station 112. A lifting device 20 then transfers the oil tank 200 from the unloading station 112 to the welding line. Multiple cooling devices 12 cool the oil tank 200 located at these multiple cooling stations, reducing the risk of excessively high oil tank temperatures and ensuring the welding line can weld oil tanks 200 at the expected temperatures. The conveying device 11 and the multiple cooling devices 12 are located at the top of the welding line, reducing the floor space required and enabling cooling of the oil tank 200 within a limited space, thereby improving the welding quality of the oil tank 200.

[0029] Please see Figures 1 to 4 , Figure 4 yes Figure 3 The image shows a front view of a portion of the structure of the transmission device 11 and the cooling device 12. In one embodiment of this invention, the cooling device 12 includes a first fan 121 located on the bottom side of the transmission device 11. A first air duct 1211 is provided on the side of the first fan 121 facing the transmission device 11. The axis of the first air duct 1211 is parallel to the vertical direction, and the first air duct 1211 is used to output airflow to the oil tank 200.

[0030] Specifically, the axis of the first air duct 1211 is parallel to the Z direction. The first fan 121 includes a housing, a rotary motor, and blades. The first air duct 1211 is opened in the housing and passes through the housing along the Z direction to connect the two sides of the housing along the Z direction. The blades are rotatably disposed in the first air duct 1211. The rotary motor is connected to the blades and can drive the blades to rotate around an axis parallel to the Z direction to transport gas from the side of the first fan 121 away from the transmission device 11 through the first air duct 1211 to the transmission device 11.

[0031] Understandably, the first fan 121 can deliver airflow vertically upwards towards the oil tank 200. The oil tank 200 is typically irregular in shape. By using the first fan 121 to output airflow to the oil tank 200 to cool it, the contact between the cooling device 12 and the oil tank 200 can be reduced. On the one hand, this eliminates the need for a structure adapted to the shape of the oil tank 200 to contact it for cooling, thus reducing costs. On the other hand, it reduces the risk of the oil tank 200 being damaged by the cooling device 12 during the cooling process.

[0032] It should be noted that as the air temperature rises, the air density decreases, allowing the warmer air to rise relative to the cooler air. The first fan 121 is located at the bottom of the oil tank 200. The first fan 121 can deliver the low-temperature air at the bottom towards the oil tank 200, so that the low-temperature air cools the oil tank 200 and causes the air heated by the oil tank 200 to move upward. This arrangement can reduce the risk that the air heated by the oil tank 200 will be drawn into the first fan 121, thus reducing the cooling efficiency of the oil tank 200.

[0033] Please see Figures 3 to 5 , Figure 5 yes Figure 3 A three-dimensional structural schematic diagram of the second fan 122 and the guide member 123 is shown. In one embodiment of this implementation, the cooling device 12 includes a second fan 122 and a guide member 123. The guide member 123 has a guide surface 1231 inclined to the vertical direction. The guide member 123 is located on the top side of the transmission device 11. The second fan 122 is located on the side of the guide member 123 facing away from the transmission device 11. The second fan 122 is used to output airflow to the oil tank 200.

[0034] Specifically, the guide surface 1231 is parallel to the Y direction and inclined to the Z direction, and the guide surface 1231 is located on the side of the guide member 123 facing the transmission device 11. The second fan 122 includes a rotary motor and blades. The rotary motor of the second fan 122 is connected to the blades and can drive the blades to rotate so that the second fan 122 can deliver airflow to the oil tank 200.

[0035] It is understandable that the first fan 121 can cool the bottom of the oil tank 200, and the second fan 122 can cool the top of the oil tank 200. By setting the second fan 122 on the top of the transmission device 11, on the one hand, the cooling efficiency of the oil tank 200 can be improved, and on the other hand, the temperature of the top and bottom of the oil tank 200 can be made more consistent, so as to reduce the risk of the oil tank 200 cracking due to uneven temperature.

[0036] It should be noted that the airflow delivered by the first fan 121 to the oil tank 200, after being heated by the oil tank 200, may flow along the Z-direction to the second fan 122 and be delivered to the oil tank 200 by the second fan 122. This would result in the airflow delivered by the second fan 122 to the oil tank 200 having a higher temperature, thus reducing the cooling efficiency of the top of the oil tank 200. Positioning the second fan 122 on the side of the guide vane 123 facing away from the transmission device 11 serves two purposes. First, the guide vane 123 can isolate the airflow output by the first fan 121 from the second fan 122, reducing the risk of the second fan 122 delivering hot air to the top of the oil tank 200. Second, the guide surface 1231 can guide the airflow output by the first fan 121 along a direction inclined to the Z-direction, reducing the risk of the airflow output by the first fan 121 rebounding towards the oil tank 200 of the transmission device 11, and also reducing the risk of the airflow rebounding towards the welding line. This configuration, on the one hand, helps to further improve the cooling efficiency of the oil tank 200, and on the other hand, reduces the risk that the hot air generated by the cooling line 10 will heat up the oil tank 200 of the welding line.

[0037] Please see Figures 3 to 5 In one embodiment of this implementation, the second fan 122 is provided with a second air duct 1221, the axis of the second air duct 1221 is parallel to the guide surface 1231, and the second air duct 1221 is used to output airflow.

[0038] Specifically, the second fan 122 includes a housing, a second air duct 1221 is opened in the housing, the rotating motor of the second fan 122 and the blades of the second fan 122 are both arranged in the second air duct 1221, the axis of the second air duct 1221 is perpendicular to the X direction and inclined to the Z direction.

[0039] It is understandable that the second air duct 1221 can output airflow along the axial direction of the second air duct 1221 toward the oil tank 200. By opening the second air duct 1221, it is beneficial to control the direction of the airflow output by the second fan 122.

[0040] Please see Figures 3 to 5 In one embodiment of this implementation, the conveying device 11 includes a conveyor belt extending perpendicular to the horizontal direction, and a plurality of cooling devices 12 are arranged in the horizontal direction. The conveyor belt is used to transport the oil tank 200 in the horizontal direction.

[0041] Specifically, the transmission device 11 includes three transmission belts, which correspond one-to-one to form a first conveyor line 113, a second conveyor line 114, and a third conveyor line 115.

[0042] Understandably, all three conveyor belts extend along the X direction, and the three sets of cooling devices 12 are arranged one-to-one along the three conveyor belts. The multiple cooling devices 12 are arranged at intervals along the X direction so that the conveyor belts can drive the oil tank 200 to pass through multiple cooling devices 12 in sequence. This arrangement can improve the cooling effect on the oil tank 200.

[0043] It should be noted that in some embodiments, in the arrangement of multiple cooling devices 12, multiple guide surfaces 1231 are parallel to each other, and the axes of the second air ducts 1221 of multiple second fans 122 are parallel and all parallel to the guide surfaces 1231. This can reduce the risk that the airflow output by the second fan 122 of the preceding cooling device 12 intersects with the airflow direction guided by the guide surface 1231 of the following cooling device 12. This arrangement can reduce the risk of airflow turbulence leading to a decrease in the cooling efficiency of the oil tank 200.

[0044] Please see Figures 1 to 2 , Figure 6 , Figure 6 yes Figure 1 A schematic diagram of part of the structure of the lifting device 20, the lifting drive assembly 31, and the lifting assembly 32. In one embodiment of this implementation, the lifting drive assembly 31 and the lifting assembly 32 are further included. The lifting assembly 32 and the clamping mechanism 22 are arranged horizontally at intervals and are used to connect the oil tank 200. The lifting drive assembly 31 is connected to the lifting assembly 32 and can drive the lifting assembly 32 to move vertically, so that the lifting assembly 32 transfers the oil tank 200 from the front line to the loading station 111.

[0045] Specifically, the lifting drive assembly 31 includes a linear motor with a drive direction parallel to the Z direction, and the lifting assembly 32 includes a gripper and a clamping driver. The clamping driver is connected to the gripper and can drive the gripper to clamp the oil tank 200. The lifting assembly 32 is located on one side of the loading station 111 along the Y direction.

[0046] It should be noted that during the manufacturing process of the fuel tank 200, the pre-processing of the fuel tank 200 is usually completed through a pre-processing line. During the processing of the fuel tank 200 by the pre-processing line, the temperature of the fuel tank 200 will rise, and the pre-processing line is usually arranged at intervals along the horizontal direction with the welding line.

[0047] It is understandable that by setting up lifting components 32 spaced apart from clamping mechanism 22, the oil tank 200 can be clamped from the front line body by the lifting components 32. The lifting drive component 31 can drive the lifting components 32 to move along the Z direction, so that the lifting components 32 can transfer the oil tank 200 from the front line body to the loading station 111 along the Z direction, and the transmission device 11 can transport the oil tank 200 from the front line body to the cooling device 12. This arrangement allows the welding station 100 above the cooling line to cool and weld the oil tank 200 of the front line body, which is beneficial to improving adaptability.

[0048] Please see Figure 6 and Figure 7 , Figure 7 yes Figure 1 A three-dimensional structural schematic diagram of the clamping mechanism 22 is provided. In one embodiment of this implementation, the clamping mechanism 22 includes a clamping member 221, a clamping driver 222, an adjustment driver 223, and a plurality of elastic clamping blocks 224. The clamping member 221 is movably connected to the transmission device 11. The lifting drive mechanism 21 is connected to the clamping member 221 and can drive the clamping member 221 to move in the vertical direction. The plurality of elastic clamping blocks 224 are movably disposed on the clamping member 221. The clamping driver 222 is connected to the elastic clamping blocks 224 and can drive the elastic clamping blocks 224 to move in the horizontal direction so that the plurality of elastic clamping blocks 224 clamp the oil tank 200. The adjustment driver 223 is connected to the clamping member 221 and can drive the clamping member 221 to rotate about an axis parallel to the vertical direction.

[0049] Specifically, there are two clamping drivers 222. The clamping driver 222 is a linear driver with a driving direction parallel to the X direction. The adjusting driver 223 is a rotary driver with a driving shaft parallel to the Z direction. The driving end of the adjusting driver 223 is connected to the clamping member 221. The clamping driver 222 is mounted on the clamping member 221. There are four elastic clamping blocks 224. The four elastic clamping blocks 224 are divided into two groups. The two groups of elastic clamping blocks 224 are mounted one-to-one on the driving ends of the two clamping drivers 222.

[0050] It should be noted that the two clamping actuators 222 can drive two sets of elastic clamping blocks 224 to move relative to each other in the X direction, so that the two sets of elastic clamping blocks 224 abut against the oil tank 200 and clamp the oil tank 200 located between the two sets of elastic clamping blocks 224. The adjusting actuator 223 can drive the clamping member 221 to rotate about an axis parallel to the Z direction, so that the clamping member 221 drives the oil tank 200 to rotate about an axis parallel to the Z direction. It should be understood that in some embodiments, the elastic clamping block 224 is a rubber block that can undergo elastic deformation, and in other embodiments, the elastic clamping block 224 is a foam block.

[0051] Understandably, when the elastic clamping block 224 comes into contact with the oil tank 200, it can undergo elastic deformation to fit against the surface of the oil tank 200. On the one hand, this can reduce the risk of difficulty in clamping the oil tank 200 due to its irregular shape. On the other hand, when the elastic clamping block 224 fits against the surface of the oil tank 200, it can restrict the rotation of the oil tank 200, thereby reducing the risk that the oil tank 200 will deflect during the clamping process, resulting in the angle of the oil tank 200 not being as expected when it is transferred to the transmission device 11. This can further reduce the risk that the cooling effect on various parts of the oil tank 200 is not as expected.

[0052] Please see Figure 1 and Figure 2 In one embodiment of this implementation, an isolation plate assembly 41 is also included, which is located on the top side of the welding line, and the cooling line 10 is located on the side of the isolation plate assembly 41 facing away from the welding line.

[0053] Specifically, the isolation plate assembly 41 includes multiple isolation plates with their surfaces perpendicular to the Z direction, and the multiple isolation plates are spliced ​​together to form the isolation plate assembly 41.

[0054] Understandably, by setting up the isolation plate group 41, the risk of heat convection between the cooling line 10 and the welding line can be reduced, thereby reducing the risk that the temperature of the oil tank 200 located on the welding line may not meet expectations, which is beneficial to improving welding quality.

[0055] Please see Figure 1 and Figure 2 , Figure 6 In one embodiment of this implementation, the welding station 100 on the cooling line includes a movable plate 42 and a movable driver 43. The isolation plate group 41 has a conveying port 411, which connects the two sides of the isolation plate group 41 in the vertical direction. The movable plate 42 is movably connected to the isolation plate group 41. The movable driver 43 is connected to the movable plate 42 and can drive the movable plate 42 to move to the open position and the closed position. In the closed position, the movable plate 42 covers the conveying port 411. In the open position, the conveying port 411 is exposed. The clamping mechanism 22 can move to both sides of the isolation plate group 41 through the conveying port 411.

[0056] Specifically, the conveying port 411 penetrates the isolation plate group 41 along the Z direction and connects both sides of the isolation plate group 41 along the Z direction, and the surface of the movable plate 42 is parallel to the Z direction.

[0057] Understandably, when the movable plate 42 moves to the open position, the clamping mechanism 22 can drive the oil tank 200 to move to the cooling line 10 and the welding line through the conveying port 411. When the movable plate 42 moves to the closed position, the isolation plate group 41 and the movable plate 42 work together to isolate the cooling line 10 and the welding line. This arrangement can further reduce the risk of heat convection between the cooling line 10 and the welding line without interfering with the normal movement of the lifting device 20.

[0058] It should be understood that in some embodiments, the movable plate 42 is rotatably connected to the isolation assembly about an axis parallel to the X direction, and the movable driver 43 is a rotary motor with a drive shaft parallel to the X direction. The movable driver 43 can drive the movable plate 42 to rotate about an axis parallel to the X direction to an open position and a closed position.

[0059] Please see Figure 1 and Figure 2 , Figure 6 In one embodiment of this implementation, the movable plate 42 and the isolation plate group 41 are movably connected in the horizontal direction.

[0060] Specifically, the movable plate 42 and the isolation plate group 41 can be slidably connected relative to each other along the X direction, and the movable driver 43 is a linear driver with the driving direction parallel to the X direction.

[0061] Understandably, the movement of the movable plate 42 will cause air movement, thereby generating turbulent airflow. The movable actuator 43 can drive the movable plate 42 to move in the X direction to the open and closed positions, which can reduce the component of the turbulent airflow in the Z direction, thereby further reducing the risk of thermal convection between the cooling line 10 and the welding line.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
